While I did do my best to make sure the rail was actually 45 degrees, I realized it didn't entirely matter. The top rail is there for one reason: to support the edge of the plane as it slides across the jig. As long as the sole of the plane is 45 degrees to the bed of the jig, nothing else really matters about the rail. It could be square, as long as it holds the plane at the correct angle. Once I had the angle planed in, I used my #5 plane to figure out where it should be attached, and screwed it down. I may take it up and glue it, but it seems to be fine the way it is.
And that's it... the only thing left is to try it out.
|The holdfast on the left doesn't add much, but it does at a little bit of downward pressure, which is a plus.|
|Yep, my bench is a mess. Here's how the jig looks with a plane sitting on it, though.|
|Shaving from 1/4" poplar. It works, and I'd say the plane is probably sharp enough.|
Now that I know the thing works, I'll add a rail to the bottom that I can clamp in my leg vise. That should simplify work holding quite a lot, and make it a lot quicker to set up.
Overall, a successful project!
